The mission is mentioned in some images of classified folders in the strategy guide for Return to Castle Wolfenstein. The introduction to the guide suggests that Wolfenstein 3D takes place before Return to Castle Wolfenstein.

Tides of War and Wolfenstein 3D Classic place the events of Wolf 3-D as a 'second campaign' (or 'later' campaigns) after Return to Castle Wolfenstein. Wolf 3-D Classic dates the events of the later campaigns at Feburary, 1945 (including Spear of Destiny).

Wolfeinstein (2009) appears to suggest that events of Wolfenstein 3D may have occured before the game, in particular the graphic novels released alongside the game's release. With the order being Spear of Destiny, Wolf 3D, & RTCW (or Spear of Destiny, RTCW, Wolf 3-D).
